Abstract:
Gold "nano-bullets" could seek and destroy inoperable human cancers, suggest new studies by US scientists. The tiny silica particles are plated with gold and heat up when near infrared light (NIR) is shone on them. This kills the cancer cells. Tests on human breast cancers, both in the test tube and in tumours in mice, were highly successful, the researchers report in the Proceedings of the National Academy of Sciences.
